This is some odd behavior…
I have a Particle SOP in a Geo, being rendered by a Render TOP which is the background of a Container Panel. Everything is fine, but when I add a mouse position listener to the Container (using a Panel CHOP or a Panel Execute DAT), moving the mouse over the Container speeds up the particle simulation.
When the mouse stops moving, the particles return to normal speed. When moving the mouse continuously, the speedup looks like at least 2X, maybe more.
The network is simple (~5ms cook time) and framerate is always 60.
Particle count is about 120
